SolarEnergies.ca released a new investigative homeowner briefing this week after documenting a repeat pattern across Greater Victoria: roof moss removal that appears successful, then regrowth that returns fast in shaded, debris-prone roof zones. SolarEnergies.ca is directing readers to the full report and its free online roof-and-solar estimator, which is intended to help households compare real quotes and long-term maintenance costs before committing.

“Moss is not a one-time event in Victoria. It’s a repeat bill unless the conditions change,” Vitaliy Lano stated, referencing Environment and Climate Change Canada climate normals that show roughly 155 days per year with measurable precipitation in the Victoria area, a level of moisture that gives spores plenty of chances to re-establish on shaded shingles.
The release, written by Vitaliy Lano and published by SolarEnergies.ca, compiles pricing signals from local service providers, roof-care guidance from industry sources, and solar performance research that connects roof cleanliness to real energy yield. It also outlines a practical “prevention-first” schedule designed for coastal Canadian conditions, meant to reduce repeat heavy cleanings and lower the odds that solar installs get delayed by roof surprises.
Lano, a solar consultant with years of experience in residential projects across Canada, said the report was built from the same friction points seen during solar intake calls: homeowners planning a 25–30 year solar investment while standing on a roof maintenance cycle that resets every few years. “Solar upgrades tend to expose the roof’s weak spots,” Lano commented. “If the roof edge stays wet, gutters overflow, and shaded slopes never dry, moss keeps returning. That is not bad luck. That is predictable.”
SolarEnergies.ca pointed to a second motivator behind the briefing: performance losses that homeowners often blame on weather alone. A September 2025 fact sheet from the IEA PVPS program describes soiling as a major cause of PV underperformance and estimates average global energy losses of about 4% to 7% from soiling, which can include biological debris such as lichen and moss.
“A few percent sounds small until it shows up on every bill for years,” Lano added. “Solar should feel rewarding. That gets harder when roof and array maintenance is ignored.”
The briefing also criticizes common “fast clean” methods that may look good immediately but can shorten shingle life. The Asphalt Roofing Manufacturers Association warns against using a pressure washer on asphalt shingles, a point SolarEnergies.ca highlights because it continues to show up in DIY advice and rushed service quotes.
Local service providers also echo that caution in their own materials, including warnings that pressure-based methods can worsen roof issues when moss has wedged beneath shingles.
“Pressure is tempting because it looks dramatic,” Lano expressed. “But granules are the roof’s protection. Lose them, and the roof pays the price later.”
On pricing, SolarEnergies.ca noted that Greater Victoria homeowners can see wide ranges depending on roof pitch, access, height, and severity. One Victoria-area company advertises moss removal starting at $550+ with a stated guarantee window, while other local providers publish ranges that scale based on square footage and complexity.
“The price swings are not random,” Lano suggested. “Steep roofs, tight access, heavy shade, and neglected gutters always inflate the quote. The report pushes homeowners to compare scope, not just a dollar amount.”
The report’s central claim is that most “moss removal” purchases are really visibility fixes unless they include steps that reduce roof wet time: gutter flow restoration, valley debris removal, selective shade reduction, and a follow-up prevention plan timed around leaf drop. SolarEnergies.ca describes this as a shift away from “surprise cleanings” and toward routine inspections that keep small regrowth from turning into another full scrape.
Where homeowners want an added layer of prevention, the briefing discusses water-repelling roof treatments marketed as ways to reduce moisture retention on shingles. SolarEnergies.ca cited GoNano’s published claims of 10–15 year warranty periods on shingled roof applications under certain conditions, along with its published pricing reference of about $1.15–$1.30 per square foot in one promotional estimate.
The briefing also notes that third-party dealers commonly present different price points and timelines, and urges homeowners to ask for written terms, compatibility notes, and what maintenance still applies.
“Treatments are not magic,” Lano said. “They can be useful if they reduce how often aggressive cleaning happens. But shade, debris, and gutters still run the show.”
SolarEnergies.ca also addresses a solar-specific version of the problem: moss and debris accumulating under and around panels, where airflow is reduced and access is limited. The briefing encourages homeowners planning solar to treat roof preparation as part of the solar investment, since removing and reinstalling panels for roof work is typically more disruptive than doing roof care first. “The best time to handle moss is before racking hardware goes on,” Lano stated. “It’s easier, cheaper, and it protects the long-term plan.”
To support homeowners comparing next steps, SolarEnergies.ca noted it has developed a free online tool that lets users enter an address and upload roof images for a fast remote review. The tool is designed to show realistic savings scenarios, local-style quote expectations, and financing options for qualified applicants. “Better decisions happen when the math is visible,” Lano commented.
